Ben Gordon revealed Friday he has left agent Billy Ceisler for Raymond Brothers.

Gordon's move, which hasn't cleared the players' association office yet, comes as his window for a long-term contract extension opens this summer.

Gordon, as is his nature, smiled slyly and stayed quiet as reporters attempted to gauge his asking price. Neither his deal nor Luol Deng's needs to be extended because the Bulls own both players' rights through the 2008-09 season and already have exercised fourth-year options on them.

Sources familiar with the negotiation said general manager John Paxson front-loaded Andres Nocioni's five-year contract. This move was done in the hope extensions can be reached with Gordon and Deng, both of whom should command big money.
